| Objective: By analyzing the data of the third China’s National Physical Fitness Surveillanceof cities in Liaoning province, we described the blood pressure distribution and physical fitnessstatus of people aged20-69years, and compared the physical fitness status for people with thedifferent blood pressure levels, and identified factors which influenced blood pressure levels.The study could provide a theoretical basis for the China’s National Physical Fitness Surveillanceto play key roles in the prevention and treatment of hypertension.Methods: By using stratified cluster random sampling method, a total of5817people aged20-69years in the monitoring cities of Liaoning province (Shenyang city, Dandong city, andChaoyang city) were selected as subjects. Parameters of anthropometry, physiological function,and physical constitution were determined according to the National Physical Fitness Assessment(NAPFA) standards. Three age groups were defined as follows: adult group A (20-39years),adult group B (40-59years), and elder group (60-69years). Three blood pressure levels such asnormal blood pressure, high normal blood pressure, and hypertension were classified by thecriteria of the World Health Organization/International Society of Hypertension League (1999).Results:(1) For people aged20-69years in cities of Liaoning province, the prevalence of the normalblood pressure, the high normal blood pressure, and hypertension were58.1%,17.0%, and24.9%, respectively. The prevalence of the normal blood pressure, the high normal bloodpressure, and hypertension were71.7%,13.6%and14.7%in the adult group A, and were50.4%,18.7%and31.0%in the adult group B, and were39.3%,22.3%and38.3%in the elder group.(2) In the adult group A, rate reaching the NAPFA standards (including excellent rate,superiority rate, and pass rate) in the normal blood pressure group was80.4%which wassignificantly higher than that in the high normal blood pressure group (71.2%), and hypertensiongroup (58.3%)(χ2=14.82，χ2=86.72). In the adult group B, rate reaching the NAPFA standards inthe normal blood pressure group was82.2%which was significantly higher than that inhypertension group (75.3%)(χ2=15.65). In the elder group, rate reaching the NAPFA standardsin the normal blood pressure group was91.7%which was significantly higher than that inhypertension group (84.3%)(χ2=9.82). All of the P<0.05.(3) Anthropometric parameters for both men and women in the adult group A and B, mean of body mass index (BMI) and waist-to-hip ratio (WHR) in hypertension group, the high normalblood pressure group, and the normal blood pressure group showed an significantly increasingtendency. In the elder group, mean of BMI and WHR in hypertension group were significantlyhigher than those in the normal blood pressure group. Physiological functional parameters forboth men and women in the adult group A, the adult group B, and the elder group, mean heartrates in hypertension group were significantly higher than those in the normal blood pressuregroup. In the adult group A of men, vital capacity per weight of hypertension group wassignificantly lower than those in the normal blood pressure group. Parameters of physicalconstitution for both men and women in the adult group A, the adult group B, and the eldergroup, choice reaction time in hypertension group, the high normal blood pressure group, and thenormal blood pressure group showed an significantly increasing tendency. All of the P<0.05.(4) Results of influencing factors for the high normal blood pressure showed that risks ofsubjects with high normal blood pressure were1.03(95%CI:1.02-1.04) times higher withincreasing per standard deviation of age, and the risks of high normal blood pressure were1.02(95%CI:1.01-1.02) times higher with increasing per standard deviation of heart rate.Furthermore, the risks of subjects in the overweight group were1.34(95%CI:1.11-1.61), and1.89(95%CI:1.41-2.54) times higher to development of the high normal blood pressure andhypertension than those with normal BMI, respectively. Risks in women to development of thehigh normal blood pressure were0.50(95%CI:0.41-0.62) times lower than that in men.Moreover, risk of subjects with high normal blood pressure were0.99times (95%CI:0.98-0.99)lower with increasing per standard deviation of step-test index. All of the P<0.05.(5) Results of influencing factors for hypertension showed that risks of subjects withhypertension were1.05(95%CI:1.04-1.06) times higher with increasing per standard deviationof age, and the risks of hypertension were1.03(95%CI:1.02-1.04) times higher with increasingper standard deviation of heart rate, and the risks of hypertension were1.03(95%CI:1.01-1.06)times higher with increasing per standard deviation of choice reaction time. Risks for subjects todevelopment of hypertension increased1.04(95%CI:1.04-1.06) times with increasing perstandard deviation of waist circumference. Furthermore, the risks of subjects with abdominalobesity were1.52(95%CI:1.27-1.82) times higher to development of hypertension than thosewith normal waist circumference. Compared to the risks of subjects with normal BMI, the risksof subjects in the overweight group and the obesity group were1.79(95%CI:1.50-2.14), and 4.19(95%CI:3.24-5.42) times higher to development of hypertension. Risks in women todevelopment of hypertension were0.36(95%CI:0.29-0.44) times lower than that in men. Riskof subjects with hypertension were0.92times (95%CI:0.97-0.98) lower with decreasing perstandard deviation of vital capacity per weight. Moreover, risk of subjects with hypertensionwere0.98times (95%CI:0.98-0.99) lower with increasing per standard deviation of step-testindex. All of the P<0.05.Conclusions:(1) The prevalence of the high normal blood pressure, and hypertension are both at higherlevels in people aged20-69years in cities of Liaoning province.(2) Rates of reaching the NAPFA standards (including excellent rate, superiority rate, andpass rate) in the normal blood pressure population are higher than the high normal blood pressurepopulation and hypertension population in people aged20-69years in cities of Liaoningprovince.(3) Blood pressure levels are related with physical fitness in people aged20-69years incities of Liaoning province.(4) The risk factors for the high normal blood pressure are age, heart rate and BMI, whilethe protective factors are women and step-test index. The risk factors for hypertension are age,heart rate, choice reaction time, BMI, waist circumference, abdominal obesity, while theprotective factors are women, vital capacity per weight, and step-test index. |
